Rotavapor® R-300

Convenient and efficient rotary evaporation

The R-300 meets the highest expectations in convenience and versatility. Its modular design allows extension of the Rotavapor® R-300 to a fully integrated system where a central interface regulates each component.

Where is the rotation speed displayed?

The rotation speed, as well as heating bath temperature and lift position, are shown on the integrated bath display. When using an interface those parameters are shown on both the bath and the interface.

Which liquid should be used in the heating bath?

Tap water is the most common used fluid. When using distilled water, 0.5 g of Borax should be added. Distilled water without any additionally added ions will corrode the bath. For heating temperatures higher than 95 °C we recommend polyethyleneglycol (PEG).

Why are there some condensate droplets on the diaphragm?

If the distillation parameters are not chosen according to the "delta 20 rule" (10-30-50), the condensation is not complete and vapor is entering into the pump. Due to the high vacuum in the second stage, the vapor may condensate, leading to droplets. Thus, the pressure has to be increased or the cooling temperature of the condensation assembly decreased.
